A suburb is an area located on the edge of a large city or town and inhabited by people who work in those cities or towns.
Generally, suburbs are less densely populated when compared to inner city neighbourhoods, central cities, and business districts. Historically, in the 19th and 20th centuries, the level of commuting increased due to the rapid improvement in rail and road transport, hence the concept of suburbs.
Asides residential suburbs, other exceptions include planned communities, satellite cities, and industrial suburbs. The proliferation of suburbs is well pronounced in the towns with a plethora of adjacent flatlands. Very few countries around the world have more suburbs, some of which include the United States, Australia, and New Zealand.
